Ukusetyenziswa kweI-Hydroxypropyl Methyl CelluloseUkuprintwa kwe-Ink
I-inki yenziwe ngee-pigments, ii-binders kunye nee-assistant agents (i-hydroxypropyl methylcellulose), ezixutywayo kwaye ziqengqelwe
Ilungele i-inki. Umbala, umzimba (ngesiqhelo iipropati ze-rheological ze-inki ezifana nokuqina okuncinci kunye nokugeleza kwamanzi zibizwa ngokuba yi-body of ink) kunye nokusebenza kokomisa zezona mpawu zintathu zibalulekileyo ze-inki.
I-instant hydroxypropyl methylcellulose yokuprinta i-inki yipowder emhlophe engenavumba, engenancasa, engenatyhefu.
Iyanda ibe yisisombululo se-colloidal esicacileyo okanye esinamafu kancinci emanzini abandayo. Ineempawu zokutyeba, ukubopha, ukusasazeka, ukuxuba, ukwenza ifilimu, ukumiswa, ukufunxa, ukugaya, umsebenzi womphezulu, ukugcinwa kwamanzi kunye ne-colloidal ekhuselayo. Idlala indima ebalulekileyo.

I-Hydroxypropyl methylcellulose ine-viscosities ezintathu ze-100,000, 150,000, kunye ne-200,000. I-viscosity luphawu lokuhamba kolwelo lwe-inki.
Isalathisi sobungakanani bokumelana (okanye ukungqubana kwangaphakathi) kwintshukumo. Kwinkqubo yokuprinta ngaphandle, kufuneka i-viscosity ethile ukuze i-inki ikwazi ukudluliselwa ngendlela eqhelekileyo.
Yimeko ephambili yokuhanjiswa nokudluliselwa, kwaye ikwayimeko ebalulekileyo yokumisela ukukhawuleza, ukucaca kunye nokukhazimla kokushicilela.
Ukuba inkulu kakhulu, kuya kuba nzima ukuyidlulisela nokuyidlulisela, ukuze ubungakanani beinki kuyilo lunganeli, nto leyo ebangela ukuba imifanekiso kunye nombhalo ube mdaka ukuze kwenziwe ipateni. Ngokufanayo, i-viscosity
Ukuba inkulu kakhulu, kulula nokuba iphepha ligutyungelwe kwaye libe ngumgubo, okanye libangele ukuxobuka kwephepha eliprintiweyo. Kodwa ukuba i-viscosity incinci kakhulu, kulula ukuyivelisa.
Idada kwaye ingcolile, iya kubangela i-inki emulsification kwiimeko ezinzima, ukuba ayikwazi ukugcina ukuhanjiswa okuqhelekileyo kunye nokudluliselwa, kwaye kancinci kancinci kwi-inki
Amasuntswana e-pigment aqokelelana kwiirola, iipleyiti zokuprinta kunye neengubo, kwaye xa ukuqokelelana kufikelela kwinqanaba elithile, kuya kubangela ukuxinana.

I-Hydroxypropyl methyl celluloseinomqamelo olungileyo, ithintela ukunamathela kweyinki ngexesha lenkqubo yokuprinta
Ayihambelani nokusebenza kunye neemeko zokuprinta ze-substrate, nto leyo ebangela ukuba iphepha libe yipowder, i-lint, i-inki ingasebenzi kakuhle, kunye nokuprinta.
Ukungaphumeleli kokuprinta njengeepleyiti ezingcolileyo.

I-Hydroxypropyl methylcellulose ine-thixotropy elungileyo, ithintela i-thixotropy ye-inki ngexesha lenkqubo yokuprinta.
Ukungaphumeleli kokuprinta okufana "nokuhamba kakubi kwe-inki", ukudluliselwa kwe-inki okungalinganiyo, kunye nokwanda okukhulu kwamachaphaza okubangelwa kukubi.

I-Hydroxypropyl methylcellulose ine-adhesion ephezulu kakhulu, kwinkqubo yokuprinta ngaphandle, amandla okufaka imibala kwi-inki awapheleli nje ekukhanyeni ngokuthe ngqo.
Inxulumene nesiphumo sokuprinta kunye nomgangatho wemveliso eprintiweyo, kwaye inxulumene kakhulu nobungakanani beinki kwindawo nganye. Ukuba ukhetha.
Ukusebenzisa ii-inki ezinamandla okupeyinta kuya kusebenzisa i-inki encinci kunee-inki ezinamandla okupeyinta abuthathaka, kwaye iziphumo ezilungileyo zokuprinta zinokufumaneka.

I-hydroxypropyl methylcelluloseinobumanzi obuhle kakhulu, i-inki yobumanzi efanelekileyo, kwaye ilingana nomthombo we-inki
Iyakwazi ukuyifaka kakuhle kwaye iyakwazi ukuyifaka kakuhle; ukudluliselwa kunye nokudluliselwa phakathi kweerola zeinki okanye phakathi kwepleyiti yokuprinta kunye nengubo nako kulungile;
Umaleko we-inki uyafana; ifilimu ye-inki eprintiweyo ithambile kwaye igudile. Ukuba ukunyibilika kwayo kuncinci kakhulu, kulula ukubangela ukukhupha i-inki kakubi; ukusasazwa okungalinganiyo komaleko we-inki, njl.
isiganeko, umphezulu wefilimu ye-inki eprintiweyo uya kubonakala namaqhuqhuva. Xa ulwelo lukhulu kakhulu, umaleko we-inki obhityileyo kulula ukubangela ukwanda kwamachaphaza, ukuprinta
Umbala awunamandla. Indlela ye-flow meter isetyenziswa kakhulu.
